I just had a 1 hour talk with applecare about this. I was esclated through several levels.
They are not reporting an issue with the iTunes Match service but I can nolonger add a device to iTunes match and they have no idea why.
I still have an open ticket. But no known resolution... So I am betting it is a server side issue that Apple is not reporting.

It is not working again. I have had problems syncing since iOS 6; when it does work, it is sporadic at best and always unpredictable. Most of the time, I cannot sync the many thousands of songs in the iTunes Cloud with any device; the result is that even songs I uploaded from legal CD's cannot be played on any Apple device.
